1 Claim. (Cl. 4-43) The present invention relates to a new mechanical device for filling toilet tanks with water, retaining it therein without leaks, and discharging the water therefrom.

A further feature of the invention resides in the fact that the mechanism has no moving parts which, due to wear or disadjustment, allow the water to run out or impair the good performance of the whole device.

Another advantage consists in that the utilization of the invention suppresses the points through which the water might filter or leak, with a consequent economy in consumption due to the absence of waste.

Figure 1 shows a front view of the mechanism inside a toilet tank.

Figure 2 presents the mechanism inside the tank, as seen from above.

Figure 3 shows the mechanism of the invention in side view.

This new mechanism consists of a water feed pipe, 1, which is secured hermetically to the base of the tank and serves as a support for valve 3 which regulates the feeding of water into the tank through pipe 2 which almost reaches the bottom. Said valve 3 operates by means of a float 5 to which it is joined by rod 4. From said feed pipe 1 there is derived upwardly a branch 11 which connects with valve 12, which is operated by handle 13, on the outside of the tank. To said valve 12 is connected a trompe 14 which discharges through a pipe 15 that is prolonged almost to the bottom of the tank.

From trompe 14 there extends pipe 10 which is connected at the upper part B of syphon 7, and from valve 3 there extends another pipe dwhich is connected with the same orifice B of syphon 7, which is provided, on its base, with orifices A for the entrance of water circulating from below to above and discharges through the inside of cylinder 8, enclosed within syphon 7, to fall into the cesspool 9 and from there into the toilet bowl.

The aforesaid mechanism operates in the manner indicated below, starting with the assumption that the toilet tank is empty and that it is to be filled with water and then emptied, repeating in this way the same operations for an indefinite period.

When the tank is emptied, the float 5 descends and opens valve 3 which permits the entry of water from feed pipe 1. The water is discharged through pipe 2 and pipe 6 and this small amount of water passes through the pipe of the central cylinder 8, of the syphon, to the cesspool 9 and from there to the toilet bowl, to maintain the same water level therein. The water flowing from pipe 2 will continue filling the tank until the float reaches a position in which it will close valve 3, while the water penetrates into syphon 7, through the orifices A, more or less to the same level of the upper end of cylinder 8, the inner air contained in syphon 7 escaping through the lateral orifice C.

The central cylinder 8 of the syphon rises above the bottom of the tank more or less up to the level which ice the water should have when the tank is full and it is hermetically secured at the inlet orifice so as to prevent any leakage of water, and underneath the tank it extends to cesspool 9 so that there always is water covering the lower mouth of said cylinder 8. Bell 7, due to the fact that it encloses cylinder 8, is larger in diameter than the latter, so that there will be, between the walls of both, sutficient space for the water to circulate.

When the tank is full of water up to its normal level, the air inside syphon 7 is under a certain compression, and if valve 12 is operated by means of handle 13, the feed water, flowing through pipe 11, will pass to the water trompe 14, suctioning the air found in the head of the syphon, through pipe 10, so that said air and the water from trompe 14 are expelled through pipe 15. At this time the atmospheric pressure causes the water inside syphon 7 to precipitate through cylinder 8 toward the toilet bowl, entraining with it all the water of the tank through orifices A, until the tank is completely emptied. Thereupon water will begin to flow again through pipe 2 and the operation can be repeated indefinitely.

Inner cylinder 8 serves as an overflow if, due to any reason, Valve 3 in the feed pipe should fail.

In practice different types of syphons can be made. The cesspool may be placed inside the tank, giving it a convenient form, without this modifying the spirit of the invention.

Having thus particularly described the invention, what I consider as new and desire to secure by Letters Patcut is:

A flush valve mechanism for a tank comprising a siphon within the tank, said siphon including an outer bell projecting upwardly from the bottom of the tank and formed with an inlet port near the bottom of the tank, and an air vent near its upper end spaced below the normal water level within the tank, the upper end of the bell being closed, a central vertical discharging pipe extending upwardly into said bell through the bottom of the tank and communicating at its upper end with the interior of the bell at a level above the said vent, said pipe being spaced from the bell to leave a passage around said pipe within the bell establishing communication between the upper end of the pipe and said inlet port, a liquid trap enclosing the lower end of said pipe beneath and exteriorly of the tank to provide a liquid seal at the discharge end of the pipe, communicating with the interior of the tank for delivering water thereinto, a siphon supply pipe establishing communication between the feed water pipe and the interior of said bell above the open upper end of said siphon discharge pipe, a valve interposed between said siphon supply pipe and the feed water pipe and operative to simultaneously control the flow of water from said feed water pipe both into said tank and to said siphon supply pipe, a water trompe operatively connected to said feed water pipe for actuation responsive to the injection of water into said trompe from the feed water pipe, a manually controllable valve connected between the feed water pipe and said trompe for controlling actuation of said trompe, said trompe also being operatively connected to and communicating with the interior of said bell above said vent, to create a suction therein and raise the water level above the end of said discharge pipe when actuated and thereby to trigger said siphon.
